FELLY-Bo LT.

SPECIFICATION forming part of Letters Patent No. 375,177, dated December 20, 1887.

Application filed August 3, 1887. Serial No. 246,035. (No model.)

To all whom it may concern Be it known that I, DUNCAN W. M cKINNoN, of North Sydney, in the county ofCape Breton,

Province of Nova Scotia, and Dominion of.

Canada, have invented anew and Improved Felly-Bolt, of which the following is a full, clear, and exact description.

This invention relates to a novel forni of bolt, the object of the invention being to proi@ vide a bolt that shall be useful in many connections, but one which is more especially adapted for use in connection with the fellies of vehicle-Wheelathe bolt being used to prevent the splitting of said fellies without detracting from their' general appearance; and

to the end named the invention consists of a bolt and nut formed with re'enforcing sections, the head of the bolt being nicked after the manner of an ordinary Woodscrew.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure lis a side view of a portion of a z5 Wheel, representing the same as being provided with my improved form of bolt. Fig.

2 is a sectional view taken on line x w of Fig. 1. Fig 3 is a View of the inner face of the nut as it appears when removed from the bolt, and

3o Fig. 4 is a sectional View taken on line y y of Fig. 3.

In the drawings, l0 represents a bolt that is formed with a dat head, 11, which has anick, 12, in its outer face, a re-enforcing section, 13,

being formed at the point where the shank joins the head. The end of the shank is threaded, as shown at 14, to engage the nut 15, which nut is a at disk-like body having a reenforcing section, 16, upon its inner face,

ribs or Iianges 17 being formed at the side of the reenforcing section 16.

In applying the bolt the felly of the wheel is countersunk upon cach side ot' the spoke, and an aperture is bored through the felly. The nut is inserted in one of the countersunk recesses, and the threaded portion of the boltshankis broughtinto engagement with the nut, after which the bolt is turned home by means of a screwdriver that is brought into engagement with its nick 12, the outer face of the bolthead and the outer ace of the nut 15 being brought flush with the side faces of the felly.

By applying the nut as above described the felly will be held from splitting, and the eX- posed portions of the bolt and nut,being iiush with the faces of the felly,will not detract from the general appearance of the wheel.

Although I have described this invention in connection with a felly, it will of course be understood that it could be used in many other Ways.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. The combinatiomwith a bolt formed with a nicked head and a re-enforcing section, of a disk-like nut formed with a re-enforciug section, substantially as described.

2. The combination,with a bolt formed with a re-enforcing section, 13, and a head, 11, in which there is a nick, 12, ofadisk-like nut, 15, formed with a 11e-enforcing section, 16, and with ribs 17, substantially as described.
